Jung's interest for alchemy starts from two directions. One is the necessity to find a historic parallel to his own discoveries of the unconscious psychic life. The second
refers to the series of dreams which have evoked the new research course, on which Jung talks at length in his autobiography: Memories, Dreams and Reflections.

"Before I discovered alchemy - writes Jung - I had a series of dreams which dealt with the same theme.
Beside my house stood another, that is to say, another wing of annex, which was strange to me. Each tie I would wonder in my dream why I did not know this house, although it had apparently always been there".
This strange part of the house revealed its meaning finally: "The unknown wing of the house was a part of my personality, an aspect of myself..."

This part was unconscious and would reveal itself as
an interest for the in-depth study of medieval alchemy.

This study was announced definitively in the dream from the year 1926 when Jung dreams himself being captive in the 17th
century. "Not until much later did I realize that it [the dream] referred to alchemy, for that science reached its height in the seventeenth century".

Alchemy is a symbolic representation of the

individuation process. In the serious alchemy, believes Jung, processes arising from individual psyche are described encoded. Peculiar terms that alchemy operates with, such as
prima materia, unus mundus, Mercurius, filium philosophorum, lapis and many more are decrypted by Jung through an arduous work of over 10 years.

His develops and parallels are described at length in his book Psychology and Alchemy, an essential piece of work for the ones studying interestedly analytical psychology, the individuation process and

We could resume Jung's vast experience with alchemy in the next two quotations:

- "Grounded in the natural philosophy of the Middle Ages, alchemy formed the bridge on the one hand into the past, to Gnosticism, and on the other into the future, to the modern psychology of the unconscious".

- "Only after I had familiarized myself with alchemy did I realize that the unconscious is a process, and that the psyche is transformed or developed by the
relationship of the ego to the contents of the unconscious".
